Bad Parameter Sniffing Decision Flow Chart

Lots of people are confused by how to deal with bad parameter sniffing when it occurs. In an effort to help with this, I’m going to try to make a decision flow chart to walk you through the process. This is a rough, quite rough, first draft.

I would love to hear any input. For this draft, I won’t address the things I think I’ve left out. I want to see what you think of the decision flow and what you think might need to be included. Click on it to embiggen.

Thanks to the attendees at my SQLSaturday Louisville pre-con for the great questions and the inspiration to get this done.

Thank you in advance for any and all feedback.

The Scary DBA

I have twenty+ years experience in IT. That time was spent in technical support, development and database administration. I work forRed Gate Software as a Product Evangelist. I write articles for publication at SQL Server Central, Simple-Talk, PASS Book Reviews and SQL Server Standard. I have published two books, ”Understanding SQL Server Execution Plans” and “SQL Server 2008 Query Performance Tuning Distilled.” I’m one of the founding officers of the Southern New England SQL Server Users Group and its current president. I also work on part-time, short-term, off-site consulting contracts. In 2009 and 2010 I was awarded as a Microsoft SQL Server MVP. In the past I’ve been called rough, intimidating and scary. To which I usually reply, “Good.” You can contact me through grant -at- scarydba dot kom (unobfuscate as necessary).
